Understanding Height Prediction

Our calculator uses scientifically validated methods to estimate adult height based on parental heights.

1

Mid-Parental Height Method

This method, developed by child growth experts, provides reliable height predictions by considering genetic influences from both parents. The formula includes a gender-specific adjustment to account for natural height differences between males and females.

For Boys:

(Father's Height + Mother's Height + 13) ÷ 2

Add 13 cm (5 inches) to account for male height advantage

For Girls:

(Father's Height - 13 + Mother's Height) ÷ 2

Subtract 13 cm (5 inches) to account for female height difference

Statistical Accuracy

  • Prediction Range: The calculated height typically falls within ±10 cm (±4 inches) of the actual adult height
  • Genetic Influence: Inherited factors account for 60-80% of final adult height
  • Environmental Factors: Nutrition, health care, and living conditions can influence the final adult height by 20-40%
